I have a Grails plugin that I want to run locally with Grails 2.3.x. What I did is packing the plugin folder and put it in:
/lib/myPlugin-1.0.zip
Now I can use
compile ":myPlugin:1.0"
in my plugin section of my BuildConfig.groovy file.
It worked in Grails before version 2.3 but in 2.3.x it throughs the following error:
Resolve error obtaining dependencies: Could not find artifact org.grails.plugins:prerender:zip:1.0.4 in grailsCentral (http://repo.grails.org/grails/plugins)

You can use your local plugin without adding it into lib folder, just add below mentioned line to your app BuildConfig.groovy file.
grails.plugin.location.myPlugin = "/home/user/plugins/myPlugin"
P.S. You need to add compile "myPlugin:1.0" as a dependency instead of a plugin.

Can anybody tell me what could be causing this exception?. Because it is working fine in testing environment and not in the live servers .
I tried checking the differences of test and existing prod war file, but i did not find any differences.
The major change I did was converted project from ANT to MAVEN, but not sure how this is related to this exception.

So I'm getting started with janusgraph and gremlin. I followed this guide https://developer.ibm.com/dwblog/2018/whats-janus-graph-learning-deployment/ to install and do some traverse on graph. Now i want to list all the graphs in the cassandra database with system.graphs() i got an error:
No such property: system for class: Script14

What did I do wrong and how can I fix this?
There is no notion of a system object that is native to Gremlin Server or JanusGraph which is why you're getting that error. The server simply doesn't know what that variable name is referring to.
To get the list of graph names you must use JanusGraph's ConfiguredGraphFactory at which point the syntax is:
ConfiguredGraphFactory.getGraphNames()
You can read more about that here in the JanusGraph Documentation or see the "Verify the Test Data on Your JanusGraph Deployment" section in the link you provided and pick up from there.
I am trying to migrate with application startup using the Flyway programatic API, but it seems to fail to load mysql drivers.
I am using gradle everything works fine if I use command line (presummably because I can specify the driver), but I get the following error when application starts up:

This seems to be a problem of the mysql connector. I downgraded to 6.0.+ and works fine.
compile ('mysql:mysql-connector-java:6.0.+')
I am using Jupyter Notebook on my Cloudera cluster, need to read data from hdfs. As the cluster is Kerberized so I need to get authenticated with my keytab, I ran the command inside my notebook:
kinit -kt keytab principal
no problem and I can see by klist the principal has got valid ticket
However when I attempt to access hdfs data which I am authorized to:
df_load = sparkSession.read.csv('hdfs://cmanagerdev01/user/rxie/data.csv')
I received the following error:
Py4JJavaError: An error occurred while calling o106.csv. :

I installed JavaFX (OpenJFX, Gluon JavaFX Embedded SDK 8.60.7) with the help of this thread JavaFX on ARM running jdk1.8.0 onto a Java8 SDK. I can execute simple JavaFX applications now. But when i use the WebView, the following error occurs:
pi#raspberrypi:~ $ sudo ./jdk1.8.0_91/jre/bin/java -jar fxtest.jar
Java HotSpot(TM) Client VM warning: You have loaded library /home/pi/jdk1.8.0_91/jre/lib/arm/libjfxwebkit.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
